Answer:
45
Step-by-step explanation:
You can still make the question to "How many 2-dight natural numbers are there?".
For this answer, you can memorize it and get 90.
Now, you need to make the divisible by 2 part work correctly to solve the problem. You divide by 2. so 90/2=45. The reason why you divide it by 2 is because you skip count. 2, 4, 6, 8 and 10 and so on. All even numbers are divisble by 2.
So, 45 is the answer.
A little trick:
Always when your stuck on a problem, think about what you have learned long ago. Like this: 3+3*4. You see it looks hard, but it isn't. You think what you learned before. You must do the order of operations you knew that before. So, follow PEMDAS rule. Multiplication first. 3*4=12. Now only 3 is not added so 12+3 shall be the expression. Now make the equation out of that. 12+3=15. Easy right?
